Insights

Pediatric Plasmodium vivax malaria often causes anemia and thrombocytopenia, requiring hospitalization. Prompt antimalarial treatment and supportive care led to successful recovery in all children, with no deaths.

Area of Science:

  • Infectious Diseases
  • Pediatrics
  • Hematology

Background:

  • Plasmodium vivax malaria is a significant global health concern, particularly in pediatric populations.
  • Anemia and thrombocytopenia are common complications of P. vivax malaria, potentially leading to severe outcomes.
  • Understanding the clinico-epidemiological features of these complications is crucial for effective management.

Purpose of the Study:

  • To describe the clinical and epidemiological characteristics of pediatric patients with P. vivax malaria.
  • To investigate the incidence and severity of anemia and thrombocytopenia in hospitalized children with P. vivax malaria.
  • To report treatment outcomes and complications in this patient cohort.

Main Methods:

  • Retrospective analysis of 78 pediatric patients hospitalized with P. vivax malaria over a 3-year period in Sucre, Venezuela.
  • Data collection included clinical manifestations, paraclinical evaluations (hemoglobin, platelet counts), and treatment outcomes.
  • Statistical analysis of demographic, clinical, and laboratory findings.

Main Results:

  • Fever (93.59%), anemia (94.87%), and thrombocytopenia (58.97%) were prevalent among hospitalized children.
  • Severe anemia and thrombocytopenia were observed in 10.26% and 24.36% of patients, respectively.
  • All patients were successfully discharged after treatment with chloroquine and primaquine, with no mortality.

Conclusions:

  • Plasmodium vivax malaria in children frequently presents with anemia and thrombocytopenia, necessitating hospitalization.
  • Effective antimalarial treatment and supportive care result in favorable outcomes, even in cases with severe hematological complications.
  • Persistent mild thrombocytopenia may occur post-treatment in a subset of pediatric patients.

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
Disorders of Erythrocytes01:27

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
Blood Transfusion and Agglutination02:45

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
